Absolutely. Although ScalIT actively scans emails, documents, and files stored on your company servers, that does not protect your individual computer from other external threats. It is always best to have a multifaceted defense against viruses, spyware, and other malware. ScalIT suggests always having current editions of a quality antivirus, firewall, and spyware applications, with all kept up to date. Some companies provide a holistic product that contains a whole suite of security applications within it, such as Norton 360, while others provide individual applications requiring you to assemble your own suite. Which ever method you choose, be certain to keep your security applications up to date not just with the latest virus definitions, but with the latest application engines, too. This requires you to occassionally manually check with your software manufacturers website to see if a version update is available. Most security software providers sell their products as one year subscriptions, which entitles you to any upgrades they release to their products during that year you are currently subscribed to, in addition to virus definition updates.
All ScalIT web applications are backed up on a nightly basis. Anything that you put into a ScalIT web application is backed up, so you do not need to back up items.
